Synthesis and Characterization of a Novel Lanthanide Complex with Photoluminescent and Semiconductive Properties

A novel lanthanide complex [La(2,5-PA)(2,5-HPA)(H2O)2]n · nH2O (I) (2,5-H2PA = 2,5-pyridinedicarboxylic acid) was synthesized by a hydrothermal reaction and structurally characterized by singlecrystal X-ray diffraction (СIF file CCDC no. 1570808). Complex I is characteristic of a two-dimensional (2D) layered structure with the La3+ ion coordinating with seven oxygen atoms and two nitrogen atoms to yield a slightly distorted monocapped square...
